Prior to proceeding it is important to inspect the condition of drain pipes to make sure they are not thin and frail.
Drain saddle valves are designed to be installed on standard 1-1/2" OD drain pipe. Install drain saddle valve above (and
before) the trap and on the vertical or horizontal tailpiece. Never install a drain saddle valve close to the outlet of a
garbage disposal or plugging of the RO drain line may result.
Drain saddle valve installation
Procedures
1. Position threaded half of drain saddle valve at selected location and mark for the opening.
2. Drill 1/4" hole at mark through one side of pipe.
3. Position both halves of drain saddle on drain pipe so threaded opening lines with hole.
4. Secure drain saddle clamp on valve with bolts and nuts provided. (Do not over tighten and make sure there is equal
space between saddle halves on each side.)
5. Initial tubing connections
For convenience on under counter installations it may be advisable to complete under counter hose connections at this
time.
6. RO component installation
Install RO membrane, carbon pre filer and sediment pre filter in modules of RO unit. (Refer to RO installation diagram.)
7. RO unit installation
The RO unit is normally mounted to the right or left sink cabinet sidewall, depending on where supply tank is to be
located. Generally the unit is installed at the front of the cabinet and the tank at the rear. To mount the unit, elevate it at
least 2" off the floor, level it and mark the location of mounting holes needed. Drill holes for mounting screws and install
screws, allowing the mounting bracket slots to slip over them.
Note: If the cabinet sidewalls are not solid, unit may sit on the floor with screws to keep it against the cabinet in a vertical
position.
8. Pre-fill, sanitizing and supply tank placement
Prefilling the storage tank is always recommended so there is sufficient pressure to check for leaks and sufficient water to
flush the carbon post filter. It is important to use a sanitizer (such as Clorox) so tubing, fittings, tank and the faucet will be
safe to use upon start-up.
To pre-fill storage tank follow these directions:
1. Connect storage tank to feed water line.
2. Open feed water valve and valve on tank.
3. Allow to fill for approximately three minutes.
4. Turn off feed water valve and tank valve.
5. Do not flush tank for approximately 15 minutes. The supply tank should be placed under the counter or within 10 feet of
the RO unit.
Note: Tanks are pre-pressurized at 7 psi. Prior to installation, check, add or release as required.
